Several examples of categorized data from epidemiological studies are analyzed to illustrate that more informative analysis than tests of independence can be performed by fitting models. All of the analyses fit into a unified conceptual framework that can be performed by weighted least squares. The methods presented show how to calculate point estimate of parameters, asymptotic variances, and asymptotically valid x2 tests. The examples presented are analysis of relative risks estimated from several 2 x 2 tables, analysis of selected features of life tables, construction of synthetic life tables from cross-sectional studies, and analysis of dose-response curves.

Two techniques for estimating the total number of events are reviewed in this paper. Through multiple recording of the same event (individual or animal), the Mult~ple-Record System (MRS) technique (used mainly for human populations) and the Capture-Mark-Recapture (c.m) technique (used mainly for animal populations) attempt to adjust for the incomplete coverage of single systems. The Dual Record System (DRS) technique, as a special case of the ~ms, has been used rather widely to adjust for omissions in the recording of vital events., The estimation procedure developed for the MRS and CMR have certain limitations because of their inherent assumptions and these may seriously affect the estimates obtained. The use of a log-linear model analysis for incomplete contingency tables, arising from ~ms-CMR data, as a methodological strategy for &apos;estimating the total number of events, allows choosing an estimation procedure realistically adapted to the properties of actual recording sources of information. Moreover, the incorporation of source correlation and/or event correlation into the estimation procedure can provide insight into the effects of such factors and the strengths and weaknesses of the statistical information

The ever-growing need for good estimates of the health, social political, and economic parameters of local areas has served as the motivating force for new developments in methodology. Due to the constraints of sample size, design, and cost, accessible data from large areas for criterion variables of interest is often used jointly with local data on symptomatic variables. Furthermore, several pr.ocedures have derived local area estimators by combining symptomatic information and sample data into a multiple regression format. In those situations
